Example Projects
Kalaeloa Desalination Facility
Oceanit designed the pilot facility and the full-scale facility for the Board of Water Supply, as described below. The desalination facility will occupy a portion of a 20-acre parcel. The land is undeveloped and was previously part of the Barbers Point Naval Air Station. Exploratory wells have been installed on the property, as described in the Honolulu Desalination Study Final Environmental Assessment and Finding of No Significant Impact, April 2001. The proposed desalination facility will include administration and control buildings, a chemical storage building, source water wells, pretreatment facilities, reverse osmosis facilities, a transmission main, brine pond, and reject water disposal facilities. Source water for desalination will be provided through a network of basal aquifer wells. Pretreatment may consist of chemical addition, flocculation reactors, and membrane filtration. After pretreatment, the water will then undergo reverse osmosis desalination. Product water from reverse osmosis will be conditioned before finally being pumped into the BWS distribution system. Approximately 12 million gallons per day (MGD) of source water will be pumped from the source water well network to produce 5 MGD of potable water. Reject water from pretreatment and reverse osmosis operations will be disposed of through injection wells. FLAG - Oceanit works with the City & County of Honolulu to manage sewer overflows from manholes in the system with the Fluid Level Alarm Gauge (FLAG). FLAG is a portable, easily installed unit that will send out an alarm through cellular phone, pager, or email to the pertinent people so prevention measures can be taken. I&I - Oceanit also monitors and tracks the sewer overflows for the City & County of Honolulu.
